Permit application proposes shutting down oxygen remediation system and ending its well monitoring
A permit modification application before Georgia EPD would stop the iSOC oxygen diffusion system used for groundwater remediation and eliminate the wells that track whether it is working.

What this means now
The story
A permit modification application submitted May 1, 2026 proposes a trial shutdown of the iSOC oxygen diffusion remediation system and would eliminate sampling designed to monitor the system's effectiveness after it is shut down.
The application also proposes discontinuing sampling at two Todd Creek Sentinel wells, MW-25 and MW-51.
It separately proposes discontinuing sampling at interior monitoring well MW-49.
The same application notes a statistical exceedance of the TCTL for formaldehyde at well MW-7, based on a result of 2.1 mg/L from a sample collected March 23, 2021.
